All my life I have found that the more one fears a thing, the quicker it should be done. Without heeding Marama's protests, I snapped on my glasses, tucked up my waistcloth, and went overboard. Next moment I seized the lead-line and signaled Marama to let go.

Never, before or since, have I been more afraid than on that day, as the weight took me plunging down into a bluish gloom. The bottom, as I have said, was at about eleven fathoms,—close to seventy feet,—and since the coral was of the dark-purple kind, the light was very dim. When my weight struck the coral my heart was beating so that I nearly choked; I lost my bearings and wasted half a minute before I found the entrance of the tonu's cave. Suddenly, five yards ahead of me, I perceived the dark mouth of the cavern, like a low wide doorway, fringed with pink coral and gently waving weeds. As I stared into the darkness which seemed to fill a vast chamber, I felt a prickling at the roots of my hair—what if the tonu had a mate.

Then, dimly in the gloom, I made out the forms of the two great oysters, their barnacled and crusted shells agape. I moved forward to wrench them from the rock. With one in each hand I swam toward the basket, glancing back fearfully as went. There was no shout of triumph when I reached the surface—I flung myself into the canoe and lay there while Marama pulled up the basket.

"You got them?" he inquired eagerly, without turning his head in my direction.

"They are In the basket," I said, "but if I had not found them, I would not have gone down again!"

"My stomach was cold at the thought of it. Come—let us open the shell and leave this evil place. I can scarce wait to see what is inside!"

"You take one," I suggested, "and I will open the other."

"Yes!" he answered, with a boy's eagerness to prolong the moment of suspense, "I will open mine first, and when we have seen what it contains, you can look into the other one."

He inserted his knife close to the hinge, severed the muscle connecting the shells, and laid the great oyster open on the bottom of the canoe. His fingers, skilled with long practice, went under the fringing mantle where nearly all pearls are found, searching rapidly and in vain. He felt more carefully—uttered an exclamation of disgust.

"There is nothing," he said mournfully, "not so much as a blister pearl!"
